README.md

Grafana Circle CI Go Report Card codecov

Website | Twitter | Community & Forum

Grafana is an open source, feature rich metrics dashboard and graph editor for Graphite, Elasticsearch, OpenTSDB, Prometheus and InfluxDB.

Installation

Head to docs.grafana.org and download the latest release.

If you have any problems please read the troubleshooting guide.

Documentation & Support

Be sure to read the getting started guide and the other feature guides.

Run from master

If you want to build a package yourself, or contribute - Here is a guide for how to do that. You can always find the latest master builds here

Dependencies

  • Go 1.10
  • NodeJS LTS

Building the backend

go get github.com/grafana/grafana
cd $GOPATH/src/github.com/grafana/grafana
go run build.go setup
go run build.go build

Building frontend assets

For this you need nodejs (v.6+).

To build the assets, rebuild on file change, and serve them by Grafana's webserver (http://localhost:3000):

npm install -g yarn
yarn install --pure-lockfile
npm run watch

Build the assets, rebuild on file change with Hot Module Replacement (HMR), and serve them by webpack-dev-server (http://localhost:3333):

yarn start
# OR set a theme
env GRAFANA_THEME=light yarn start

Note: HMR for Angular is not supported. If you edit files in the Angular part of the app, the whole page will reload.

Run tests

npm run jest

Run karma tests

npm run karma

Run

Recompile backend on source change

To rebuild on source change.

go get github.com/Unknwon/bra
bra run

Open grafana in your browser (default: http://localhost:3000) and login with admin user (default: user/pass = admin/admin).

Dev config

Create a custom.ini in the conf directory to override default configuration options. You only need to add the options you want to override. Config files are applied in the order of:

  1. grafana.ini
  2. custom.ini

In your custom.ini uncomment (remove the leading ;) sign. And set app_mode = development.

Running tests

Frontend

Execute all frontend tests

npm run test

Writing & watching frontend tests (we have two test runners)

  • jest for all new tests that do not require browser context (React+more)
    • Start watcher: npm run jest
    • Jest will run all test files that end with the name ".jest.ts"
  • karma + mocha is used for testing angularjs components. We do want to migrate these test to jest over time (if possible).
    • Start watcher: npm run karma
    • Karma+Mocha runs all files that end with the name "_specs.ts".

Backend

# Run Golang tests using sqlite3 as database (default)
go test ./pkg/... 

# Run Golang tests using mysql as database - convenient to use /docker/blocks/mysql_tests
GRAFANA_TEST_DB=mysql go test ./pkg/... 

# Run Golang tests using postgres as database - convenient to use /docker/blocks/postgres_tests
GRAFANA_TEST_DB=postgres go test ./pkg/...

Contribute

If you have any idea for an improvement or found a bug, do not hesitate to open an issue. And if you have time clone this repo and submit a pull request and help me make Grafana the kickass metrics & devops dashboard we all dream about!
